DPF Diagnostics

DPF Hero uses advanced diagnostics to quickly find and fix problems with Diesel Particulate Filters (DPF), keeping your engine clean and on the road. DPF diagnostics help determine if your filter is blocked, damaged, or needing regeneration, so you avoid expensive repairs or replacements.

What Is DPF Diagnostics?

DPF diagnostics is the process of checking how well your diesel filter is working. Using digital scan tools and sensors, technicians measure things like exhaust pressure before and after the filter, soot levels, and temperature differences. High pressure or abnormal temperatures often mean the filter is clogged or damaged.

How DPF Hero Diagnoses Filter Problems

• Reading Trouble Codes: DPF Hero uses software to connect to your vehicle’s computer and read any warning codes related to the filter or exhaust system.
• Pressure Testing: By measuring exhaust pressure before and after the DPF, the technician can tell if there’s too much buildup blocking airflow. High pressure means more soot; low pressure could mean a failed or cracked filter.
• Live Data Monitoring: The system checks live readings of soot mass and temperature while your vehicle is running. Unusual data signals the need for cleaning, forced regeneration, or repair.
• Visual Inspection: Technicians also check for external signs—such as leaks, physical damage, or obvious blockages in hoses and pipes.

Why Regular DPF Diagnostics Matter

• Prevents breakdowns by catching problems early.
• Saves money on fuel and future repairs by keeping your engine running efficiently.
• Keeps your vehicle legal by ensuring it meets emissions rules.
• Reduces harmful exhaust, protecting the environment and your health.

For trucks, fleets, and everyday drivers, regular DPF diagnostics by DPF Hero means less downtime, fewer surprises, and a greener, stronger diesel engine.
